The Platinum Series family of microprocessor-based PID controllers offer unparalleled flexibility in process measurement. While extremely powerful and versatile, great care has gone into designing a product that is very easy to set-up and use. The automatic hardware configuration recognition eliminates the need for jumpers and allows the firmware to automatically simplify itself, eliminating all menu options that do not apply to a specific configuration. Offered in 1⁄32, 1⁄16, and 1⁄8 DIN sizes, the 1⁄16 and 1⁄8 DIN models can be configured with dual displays.

 



Each unit allows the user to select the input type from 9 thermocouple types, PRT/RTD sensors, thermistors, DC voltage, DC current, and Strain & Bridge inputs. The full bidirectional voltage or current inputs are fully scalable to virtually all engineering units, with a selectable decimal point that is perfect for use with pressure, flow, or other process input.

Up to 6 programmable outputs including the isolated analogue and additional features make this the most powerful product in its class. Standard features include: remote set-point for cascaded control, high-high/low-low alarms, external latch reset, external ramp and soak initiation, combination heat/cool control mode and configuration save and transfer.

Free Downloadable Software
Free Downloadable Configurator Windows® Application Software
  • Fully Configure all PLATINUM Functions/Parameters
  • Auto-Connect Through USB Channel
  • Load/Save PLATINUM Configuration Files
  • Performance Tracking (Charting) with Data Capture

An advanced multi-stage ramp and soak sequencer supports up to 99 profiles of 8 segment ramp/soak sequences. Profiles may be linked to provide extended sequences and auxiliary outputs may be triggered based on individual Ramp or Soak states to provide external control over blowers, mixers or other auxiliary control functions.

Embedded Ethernet and Serial Communications
Optional “embedded ethernet” on the 1⁄16 and 1⁄8 DIN models allow the units to connect directly to an Ethernet network and transmit data in standard TCP/IP packets, or serve Web pages over a LAN or the Internet. Optional serial communications are also available configurable as RS232 or RS485, with straightforward ASCII commands or MODBUS®. All three types of communications interfaces can be installed and active simultaneously.

LabVIEW™ Driver
The Platinum LabVIEW™ driver is the National Instrument device driver for communicating with Omega Platinum Controllers via Modbus RTU/ASCII and Modbus TCP protocols. The driver allows easy access to the internal data, configuration settings, and operating functions of the Platinum product family.

The LabVIEW™ instrument driver reduces the application development time and simplifies instrument control. With the Platinum LabVIEW driver, customers can quickly communicate with the instrument and develop robust test applications and software.

DasyLab
Support for the easy-to-use DasyLab software solves complex data acquisition and control problems by allowing you to work with flowcharts directly on your PC screen. The high input accuracy, advanced process control, extended sequencing capability and flexible output options of a Platinum controller may be easily integrated with the rich set of function modules provide by the DasyLab software. The DasyLab software may be integrated thru the Platinum serial, Ethernet or USB connections.

Rated 5 out of 5 by from Best controller I have a handful of the older i16 and i32 controllers in use already, and am replacing two of those with pt32 (one done, one in progress). The i32 were already very good, with useful features, although a somewhat clunky setup interface (the 4-button menus could make grown men cry). Reliability has been perfect. Communication was a bit of an issue, required going to the larger 1/16 DIN model in some cases. The pt32 has fixed all that. Even when using the four buttons, the setup is now more logical. But the sane way to set them up is to connect them to a laptop and configure them with the Platinum program. Being able to upload and download configurations means that I can finally put the configurations under revision control, and check that the device installed in the system is actually configured correctly. I can also modify configurations offline, without taking the control system down, and then quickly upload them in a quick downtime. Once you have a configuration, it can be quickly adjusted by editing the txt file directly. All very very convenient. With the USB port, the communication problem has been solved. Find something with a USB connector nearby (laptop, industrial controller), either write a few lines of Python or install LabView, and you can chat with the controller. I'm now using the controller as an A-D converter for computer analysis of the process too. Very cool, low cost, convenient. Speaking of cost: The Newport/Omega controllers have never been cheap, but worth their price. If you need a simple low-feature controller, buy something else. The few times I've talked to tech support (in Santa Ana), they've been very helpful, patient, and knowledgeable. My only complaint is: In one case I need four setpoints and four outputs from a single input; while it is theoretically possible to get this many outputs (not clear it can be ordered in a 1/32 DIN, that would be model -444-776), there are not four setpoints available. So this needs to be handled by using two controllers. Expensive, but works great.

Rated 1 out of 5 by from Very difficult to use THS S HW YU PRGM AN OMGA CNTRLR. This is 2017. Why does the 'Platinum' temp controller have a 1980s user interface? The USB port is an afterthought in a terrible location. It would not stay connected to my computer. The software does not run in Windows 10, and is not supported by Omega. Omega makes a lot of good products, but this is not one of them. We sent the unit back.

Rated 5 out of 5 by from Love it, except one annoying little thing . . . Replaced a CNiS32 (where 4-button programming was driving me crazy) with a CN32Pt. Got it working OnOff (all I need for now) using Platinum Configurator 1.5.2.0 software in a few hours; BIG improvement over the buttons ! Using a PX309-300AV P-transducer, set scaling to give 20.7 bar at 100mV, set-point 11.0 bar. Great so far. However, cannot set deadband value smaller than 0.1; would prefer 0.05. Any way around this ? Maybe software update ?

Rated 5 out of 5 by from Excellent instruments ! We are laboratory of scientific institute and we already purchased 4 Omega Platinum controllers currently working perfectly in 4 new scientific instruments built in our lab giving millions of measurement cycles. We are going now a bit further into development and we need some more purely technical information, for instance can auto-tune be initiated over RS-232 serial protocol (which I currently could not figure out from serial protocol manual and I find command for same thing in modbus manual) and few similar questions. If we want, can we contact someone for such info ? Thank you and good job making instruments. Thomas

Rated 3 out of 5 by from Works, but not without issues Bought two controllers and ran into issues with both, readings jumped all over the place during testing. Opened up the controller and found that the input board wasn't mounted onto the main board properly for both, wasted a good amount of time trying to troubleshoot. Once I re-seated the internal board it worked as intended.

Does this model have an over set point temperature alarm or any method handling a over setpoint temperature? Looking to have the output latch off in the case of going over the set point temperature by 5 or 10 deg F. Thanks!

Asked by: ErikG
If you use the Analog output for your control loop you have a SPDT relay to use to set alarm conditions. The alarm can be used to change the color of the display or switch a light or audible device or tie to a contactor to cut current flow to your output device. It is recommended from a safety point of view to not do this because the temperature sensor is shared and if it fails your alarm relay may not work properly. A separate Limit Controller with an independent sensor is the advised way to configure for maximum safety.

Can I use this controller to maintain a heater to a variable set point temperature? The goal is to always have a sample an offset temperature from the ambient air.

Asked by: EGAtlas
Yes, if you have mA or voltage signal as input for our platinum series controller. Use the remote setpoint input feature. Then use the control offset "Ofst" function.

Thank you for your question. Use a small flat-blade screwdriver and gently pry the locking tab out on each side of the connector. Once released you can rock the connector back and forth until it comes out of the socket. I hope this helps
